I have both a full frame DSLR and a tiny ASI(1600MM) and the results are...different. On the same scope, the tiny sensor with the tiny pixels will give you better resolution on a good night, obviously at the expense of total FOV. It really depends on your angle...
The mono sensor is more versatile in that it can be effective with narrowband too...not impossible with a DSLR, but not optimal. |
Thanks for your comments, Dunk. As you say and as I have been discovering, some small CCD sensors with small pixel size can indeed deliver better results than a full frame DSLR. Just makes choosing the right camera even more bewildering!
